PurposeResearch
ObjectivesCruise 36 was planned to extend the survey of the vertical distribution of oceanic zooplankton and micro-nekton another 10N and 40N latitude. On previous cruises day and night vertical net haul series had been made at 11N, 18N and 28N. The position chosen for the present cruise, 40N 20W, had been visited by Discovery II on several occasions and materials, albeit collected by rather different methods, had been in part examined and was available in the collections for comparative purposes.
In addition further collections with the bottom longlines were planned and a new series of hauls at various depths with the bottom net. A new opening/closing net of approximately 25sq m had been made and was to be tested. A number of smaller projects were also planned.
